Can one use salon-pas patch after gastric bypass surgery since it countains has methyl salicylate?

The use of Salonpas patches after gastric bypass surgery should be discussed with a healthcare provider. While the concentration of methyl salicylate in Salonpas patches may be considered relatively low, they should use caution when using any topical products containing methyl salicylate (used for pain relief). There is a concern that the rapid absorption of salicylates through the skin can cause adverse reactions like bleeding and ulcers, especially in the early postoperative period after gastric bypass surgery.

After a gastric bypass procedure, the anatomy and mechanisms for drug absorption through the gastrointestinal tract are altered, potentially affecting the systemic bioavailability of medications. The altered anatomy might change how the body processes and absorbs methyl salicylate, and there might be increased absorption leading to potential side effects.

Therefore, it is crucial for individuals who have undergone gastric bypass surgery to consult their healthcare provider or a pharmacist before using any topical products, including Salonpas patches, containing methyl salicylate or other medications. They can assess the individual's specific situation, evaluate the potential risks and benefits, and provide appropriate recommendations for pain management after surgery.
